When there is an imbalance of the aqueous fluid either over production of the fluid or drainage channels are clogged, then pressure starts rising, once the pressure is high it damages the inner structure of the eye and the optic nerve
4 Optic nerve
is the most easily accessible part of the brain meninges and there are studies demonstrating the effectiveness of the optic nerve
sheath diameter (ONSD) on CT scans with the intracranial pressure (ICP) and the severity of the brain injury.
gov site is regarding an optic nerve
problem called NAION or Non-arteritic Ischemic Optic Neuropathy.
When two of our retinoblastoma patients, whose HP Reports only said: "cut end of the optic nerve
not involved", developed orbital and systemic metastasis; we undertook this study to do detailed HP examination of all enucleated retinoblastoma eyes and the histopathological slides.
07 The image shows the optic nerve
head of a 30-year-old woman presenting with two-day onset of a mildly painful eye and blurred vision.
Objective: To evaluate the efficacy and safety of Optic Nerve
Sheath Fenestration (ONSF) in patients with raised intracranial pressure (ICP).
The Optic Nerve
Evaluation in Glaucoma: An Interactive Workbook (online access included)
Ischemic optic neuropathy (ION) refers to infarction of any portion of the optic nerve
from the chiasm to optic nerve
Optic disc drusen (ODD) are autofluorescent, calcified deposits found in the optic nerve
head, and typically occur in small, crowded optic discs.
Glaucoma is caused by intraocular pressure (IOP) that is too high for the optic nerve
in that eye," explains Leila Rafla-Demetrious, MD, assistant professor of ophthalmology at Weill Cornell Medicine.
sheath meningioma: Current Diagnosis and Treatment.
Glaucoma is reportedly a group of diseases that damage the eye's optic nerve
and can result in vision loss and blindness.
Dr Sanjay Vodela, ophthalmic eye surgeon at Medeor 24x7 Hospital, Dubai, told Gulf News: "Glaucoma is an irreversible damage to the optic nerve
that leads to blindness in the end stage.
A search of the terms echography, ultrasound, cerebral midline, CNS ultrasound, cerebral Doppler ultrasound, optic nerve
ultrasound was conducted in the medical literature available in the Pubmed database until April 2014.
In vertebrate embryonic development, the retina and the optic nerve
originate as outgrowths of the developing brain, so the retina is considered part of the central nervous system (CNS) and is actually brain tissue.
